Data from July 17 reveals a subtle signal: the textile raw material market is not following a one-way trend, but showing significant divergence among varieties. Only two commodities posted gains—acrylonitrile and polyester staple fiber—while five declined, with PTA leading the fall at -0.44%. Although the daily average change of -0.01% is negligible, the 2:5 ratio of gainers to losers reflects growing cracks in expectations for costs and demand along the supply chain.
Behind the Moves: Variety-Level Logic
Acrylonitrile, with a daily gain of 0.35% and a year-on-year surge of 22.29%, was the most watched variety. This sustained strength stems from tight supply-demand dynamics: resilient demand from downstream carbon fiber, ABS resin, and acrylic sectors, coupled with maintenance shutdowns reducing supply. In contrast, polyester staple fiber's 0.30% gain was more cautious, its 12.73% year-on-year rise largely a byproduct of upstream PTA and MEG cost hikes rather than independent demand pull.
On the downside, PTA's -0.44% decline warrants attention. Despite its 25.68% year-on-year gain, the short-term pullback signals fatigue in absorbing high prices. Polyester POY fell 0.23%, with a year-on-year gain of 19.74%, but as a variety directly facing weaving mills, its price softening often indicates weakening downstream procurement. Raw silk's -0.14% drop, though small, with a year-on-year decline of -10.34%, underscores persistent weakness in silk end-consumption, starkly contrasting with chemical fiber varieties.
Cost Pass-Through and Inventory Cycle Game
A key contradiction emerges: PTA is up over 25% year-on-year, but polyester filament yarns (POY, DTY, FDY) show year-on-year gains of only 15% to 20%, significantly lower than the raw material increase. This means polyester margins are being squeezed. When PTA prices correct, polyester yarn prices follow suit, indicating that downstream weaving mills are not actively restocking but waiting for a lower cost window. This state of 'cost push failing to drive demand, price declines triggering wait-and-see' is a classic sign of the supply chain entering a destocking cycle.
Meanwhile, cotton-related prices remained flat across the board—cotton yarn 21S, 32S, polyester-cotton yarn, and rayon yarn showed no change. This 'silence' is not stability but a directionless stalemate. The -0.02% dip in raw cotton, combined with its 15.31% year-on-year gain, reflects a tug-of-war between expectations of new crop arrivals and current high prices. For cotton textile mills, high raw material costs without a clear uptick in final orders are delaying procurement decisions.
Industry Impact: From Price Signals to Business Decisions
For weaving and garment processing companies, the current price structure offers several key takeaways:
First, the upward momentum in polyester raw materials is waning. If PTA's short-term correction continues, it could drag down the entire polyester chain, offering a potential window for buyers planning pre-season stocking ahead of the traditional peak in August-September—but with a warning against premature 'bottom-fishing' that could lead to inventory depreciation.
Second, acrylonitrile strength may persist. For sectors using acrylic fiber or carbon fiber prepregs containing acrylonitrile, it is advisable to lock in long-term contract prices to avoid further cost escalation.
Third, the sustained weakness in raw silk and silk products suggests that home textile and garment exporters should monitor the risk of consumption downgrade for silk items in European and American markets, and consider adjusting the ratio of chemical to natural fibers in their product mix.
